Question

我正在尝试从源代码构建TensorFlow。配置安装后，当我尝试使用以下命令构建到pip包时，

$ bazel build --config=opt //tensorflow/tools/pip_package:build_pip_package

我收到以下错误消息：

ERROR: /workspace/tensorflow/core/BUILD:1312:1: Executing genrule //tensorflow/core:version_info_gen failed: bash failed: error executing command

出了什么问题？

Answer 1

您的构建似乎在

中遇到错误

tensorflow/tools/git/gen_git_source.py

在第152行。在构建的这个阶段，脚本试图获取张量流回购的git版本号。你用git来检查你的张量流回购吗？ / tensorflow / root目录中是否存在.git文件？也许你需要更新你的git版本？

即使我的:变量中有git，我也遇到了此错误。我从https://stackoverflow.com/a/5659249/212076得到了一个提示，即启动的子流程没有得到PATH变量。

解决方案是通过替换

对PATH中的git命令进行硬编码

<ROOT>\tensorflow\tensorflow\tools\git\gen_git_source.py

带

val = bytes(subprocess.check_output([
        "git", str("--git-dir=%s/.git" % git_base_path),
        str("--work-tree=" + git_base_path), "describe", "--long", "--tags"
    ]).strip())

一旦修复，我又收到了另一个错误：val = bytes(subprocess.check_output([ "C:\Program Files (x86)\Git\cmd\git.cmd", str("--git-dir=%s/.git" % git_base_path), str("--work-tree=" + git_base_path), "describe", "--long", "--tags" ]).strip())。我认为tensorflow根文件夹是应该被引用的文件夹，所以我编辑了fatal: Not a git repository: './.git'来替换

<ROOT>\tensorflow\tensorflow\tools\git\gen_git_source.py

与

git_version = get_git_version(".")

之后构建成功。
